Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a steel platform system and construction method for rapid installation and dismantling. Background Technology

[0002] Integrated jacking formwork systems (building jacks) are frequently used for wall construction in super high-rise or high-rise buildings due to their safety and efficiency advantages. Currently, the steel panels and beams of the platform at the top of the building jack are generally connected by welding. Since the platform steel panels and beams cannot be reused due to welding, the practicality of the jacking platform is reduced.

[0003] Therefore, improving the practicality of lifting platforms is a problem that needs to be solved in this field. Summary of the Invention

[0004] To address the technical problem of low practicality caused by the welding connection between the steel panels and steel beams of existing lifting platforms, the present invention aims to provide a rapid installation and dismantling steel platform system. This system can ensure the rapid installation and safe and reliable construction of the steel platform for building construction machines, while also meeting the turnover requirements of the steel platform. Furthermore, a construction method for the rapid installation and dismantling steel platform system is also developed, effectively overcoming the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides a steel platform system for rapid installation and dismantling, which includes a platform steel panel, a platform steel beam, and a connecting component. The connecting component is disposed at the end of the platform steel panel and is modularly spliced ​​with the platform steel beam through the connecting component.

[0006] Furthermore, the end of the platform steel beam is provided with multiple sets of symmetrical first connecting holes along the length direction, and the first connecting holes are used to connect with the platform steel surface in conjunction with the connecting components.

[0007] Furthermore, the platform steel panel is composed of steel plates and a structural frame, with the steel plates mounted on the structural frame and fixedly connected to it.

[0008] Furthermore, the structural skeleton includes a plurality of first longitudinal skeletons and a plurality of first transverse skeletons, which are symmetrically arranged and spliced ​​together to form a frame structure.

[0009] Furthermore, the structural frame is provided with a plurality of second longitudinal frames and a plurality of second transverse frames in the middle part. The plurality of second longitudinal frames and the plurality of second transverse frames are arranged in cooperation in the middle part of the structural frame to form a connecting body between the first transverse frame and the first longitudinal frame, thereby increasing the stress strength of the structural frame.

[0010] Furthermore, an inverted U-shaped groove is provided at the contact point between the first transverse frame and the platform steel beam, and a plurality of second connecting holes corresponding to the first connecting holes on the platform steel beam are equally spaced along the length of the U-shaped groove.

[0011] Furthermore, the first transverse frame is provided with a plurality of third connecting holes, which are configured in a one-to-one correspondence with the second connecting holes.

[0012] Furthermore, the height and width of the U-shaped groove are both greater than the component disposed on the first connecting hole.

[0013] To achieve the above objectives, the present invention provides a construction method for a rapidly assembled and disassembled steel platform system. The construction method is based on the aforementioned rapidly assembled and disassembled steel platform system and includes: laying steel plates of corresponding lengths according to different steel beam spacings, with the steel plates tightly fitted together, and the inverted U-shaped grooves at both ends of the steel plates resting on the end faces of the steel beams during the laying of the steel plates; and modularly connecting the edges and corners of the steel plates to the steel beams using connectors.

[0014] Furthermore, if there are steel beam connecting bolts below the empty space at the corner of the steel plate, move it to the adjacent position for installation.

[0015] The present invention provides a rapid installation and dismantling steel platform system and construction method. This system utilizes an inverted U-shaped groove at the contact point between the platform's steel panel and the steel beam. Connectors pass through the U-shaped groove to connect and install the platform to the steel beam. This method elevates the platform's steel panel through the U-shaped groove and avoids conflict with the flange bolts through the inverted U-shaped groove installation. This approach not only effectively solves the spatial conflict between the steel panel and the steel beam bolts but also significantly improves installation speed through steel pin installation, resulting in a reusable, rapidly installable, and structurally sound steel platform system.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0023] To address the technical problem of low practicality caused by the welded connection between the platform's steel panel and steel beams in lifting platforms, this invention aims to provide a rapidly installable and dismantled steel platform system. This system utilizes an inverted U-shaped groove at the contact point between the platform's steel panel and the steel beams. Connectors pass through the U-shaped groove to connect and install the platform to the steel beams. This method elevates the platform's steel panel through the U-shaped groove and avoids conflict with the flange bolts through the inverted U-shaped groove installation. This method not only effectively solves the spatial conflict problem between the steel panel and steel beam bolts but also significantly improves installation speed through steel pin installation, achieving a reusable, rapidly installable and dismantled, and structurally sound steel platform system. Furthermore, a construction method for this rapidly installable and dismantled steel platform system is also developed.

[0024] The rapid assembly and disassembly steel platform system provided by this invention is described in [reference needed]. Figure 1 It consists of three parts: platform steel beams 1, platform steel panels 2, and connecting components 3. The platform steel beams 1 are symmetrically arranged, and the two ends of the platform steel panels 2 cover the platform steel beams 1 and are connected to the platform steel beams 1 through the connecting components 3.

[0025] In some embodiments, the platform steel beam 1 is an I-beam, which is composed of two flanges 11 and a web 12. The two flanges 11 are symmetrically arranged on both sides of the web 12 to form an I-beam structure.

[0026] On the two wing plates 11, multiple sets of symmetrical first connecting holes 13 are provided along the length direction of the wing plates 11. The first connecting holes 13 can be used as connecting holes between the platform steel beam 1 and other building structures, and can be connected with other building structures in conjunction with bolts 14. They can also be connected with the platform steel panel 2 in conjunction with the connecting component 3. The first connecting holes 13 on the platform steel beam 1 can realize the connection of the two structures, which greatly improves the practicality of the platform steel beam 1.

[0027] Meanwhile, the first connecting holes 13 on the platform steel beam 1 are preferably distributed at equal intervals along the length of the platform steel beam 1, so that the position of the connecting component 3 can be adjusted according to the installation position of the bolts 14 on the steel beam, making the platform steel panel highly adaptable.

[0028] Further, see Figure 2 The platform steel panel 2 is composed of a steel plate 21 and a structural frame 22. The steel plate 21 is set on the structural frame 22 and fixedly connected to the structural frame 22.

[0029] The structural skeleton 22 includes several first longitudinal skeletons 221 and several first transverse skeletons 222. The several first longitudinal skeletons 221 and several first transverse skeletons 222 are symmetrically arranged and spliced ​​to form a frame structure.

[0030] Furthermore, a number of second longitudinal frames 223 and a number of second transverse frames 224 are provided in the middle of the structural frame formed by splicing a number of first longitudinal frames 221 and a number of first transverse frames 222.

[0031] In this design, a second longitudinal frame 223 and two second transverse frames 224 are respectively provided in the middle of the structural frame 22. The second longitudinal frame 223 is longitudinally located in the middle of the structural frame 22, and its two ends are respectively connected to the first transverse frame 222. The two ends of the two second transverse frames 224 are respectively connected to the first longitudinal frame 221 and the second longitudinal frame 223. The second longitudinal frame 223 and the second transverse frames 224 cooperate to form a cross-shaped structure in the middle of the frame structure, forming a connecting body between the first transverse frame 222 and the first longitudinal frame 221, which can share the force and improve the stress strength of the structural frame 22.

[0032] It should be noted that this solution is not limited to using one second longitudinal frame 223 and two second transverse frames 224. The specific number of frames used and the structure formed by their splicing can be determined according to the actual situation.

[0033] U-shaped grooves 23 are provided on the end faces of the two first transverse frames 222 of the platform steel panel 2, and the side walls of the U-shaped grooves 23 are fixedly connected to the first longitudinal frame 221, which can ensure the stability of the U-shaped grooves 23. The U-shaped grooves 23, together with the connecting components 3, can be connected to the platform steel beams 1.

[0034] Specifically, an inverted U-shaped groove 23 is provided at the contact point between the first transverse frame 222 and the platform steel beam 1. A plurality of second connecting holes 231 corresponding to those on the platform steel beam 1 are provided at equal intervals along the length of the U-shaped groove 23. At the same time, a plurality of third connecting holes 211 are provided on the first transverse frame 222. The plurality of second connecting holes 231 and the plurality of third connecting holes 211 are provided in a one-to-one correspondence and are connected to each other, which facilitates the passage of the connecting component 3.

[0035] See Figure 3 After the inverted U-shaped groove 23 on the platform steel panel 2 is placed on the wing plate 11 of the platform steel beam, the first connecting hole 13, the second connecting hole 231 and the third connecting hole 211 are connected accordingly. The connecting component 3 passes through the first connecting hole 13, the second connecting hole 231 and the third connecting hole 211 to realize the modular connection between the platform steel panel 2 and the platform steel beam 1. This solution achieves the goal of reusability of the platform steel panel 2 and the platform steel beam 1 by modular design of the platform steel panel 2 and the splicing nodes through the connecting component 3, thereby improving the economy of lifting the entire steel platform and reducing costs and increasing efficiency for the construction of high-rise building projects.

[0036] It should be noted that the U-shaped groove 23 is larger than the bolt 14 set in the first connecting hole 13 in both height and width directions. This ensures that after the U-shaped groove 23 is placed on the platform steel beam 1, the U-shaped groove 23 raises the steel plate 21, and the middle area of ​​the U-shaped groove 23 can completely cover the bolt 14 located at the bottom of the U-shaped groove 23. This avoids the contradiction between the platform steel panel 2 and the flange bolt 14. This method not only effectively solves the spatial contradiction problem between the platform steel panel 2 and the steel beam bolt 14, but also greatly improves the installation speed through the installation of the connecting component 3, realizing a reusable, quick-installation and disassembly, and stress-safe steel platform system.

[0037] The connecting components 3 are generally located at the four corners of the steel plate 21. However, if there are bolts 14 on the first connecting hole 13 of the lower plane steel beam, the position of the connecting components 3 can be moved to the corresponding position of the nearby unused first connecting hole 13, so that the platform steel panel 2 has a high degree of adaptability.

[0038] It should be noted that the structure of the connecting component 3 is not limited in this solution. This solution includes, but is not limited to, using steel pins. The specific method can be determined according to the actual situation.

[0039] Meanwhile, the structure of the structural frame 22 is not limited in this scheme. In order to ensure the strength of the frame, it is preferred to use thin-walled square steel tubes welded together. However, this scheme includes but is not limited to using thin-walled square steel tubes welded together. The specific method can be determined according to the actual situation.

[0040] The steel plate 21 is set on the structural frame 22 and fixedly connected to the structural frame 22. A steel frame system composed of square steel tubes and U-shaped channels 23 is set at the bottom of the steel plate, which reduces the span of the steel plate and increases the moment of inertia of the steel plate, resulting in less stress on the steel plate, a reasonable force path, and effectively improves the stiffness of the steel plate, thus ensuring the structural safety of the steel panel.

[0041] Meanwhile, this solution does not limit the connection structure between the steel plate 21 and the structural frame 22. It is preferred to use intermittent welding to ensure the connection strength between the steel plate 21 and the structural frame 22.

[0042] Based on the rapid assembly and disassembly steel platform system provided by the above solution, this solution also provides a construction method for the rapid assembly and disassembly steel platform system. The specific construction steps are as follows:

[0043] According to the different spacing of the platform steel beams 1, steel plates 21 of corresponding lengths are laid. The steel plates 21 are tightly fitted together. When laying the steel plates 21, it should be ensured that the U-shaped grooves 23 at both ends rest on the end face of the platform steel beams 1. The corners of the steel plates 21 are modularly connected to the platform steel beams 1 through connectors.

[0044] If there are steel beam connecting bolts 14 below the empty space at the corner of the steel plate, it can be moved to an adjacent position for installation.

[0045] The following example illustrates the specific installation process in a practical application. It should be noted that the specific installation process is for illustrative purposes only and does not constitute a limitation on this solution.

[0046] Taking the building construction machine as an example, the steel beam structure system is installed first, with the platform steel beams 1 connected by bolts. After the platform steel beams 1 are installed, steel plates 21 of corresponding lengths are laid according to the different spacing of the platform steel beams 1. The steel plates 21 are tightly fitted together, and when laying the steel plates 21, it should be ensured that the U-shaped grooves 23 at both ends rest on the platform steel beams 1. The steel plates 21 are connected to the platform steel beams 1 using steel pins. Generally, four steel pins are needed for each steel plate 21, with one pin installed at each corner. If there are steel beam connecting bolts 14 below the empty space at the corner, they can be moved to an adjacent position for installation.

[0047] The rapid installation and dismantling steel platform system and construction method described above not only effectively solves the spatial conflict between the steel panels and steel beam bolts, but also significantly improves installation speed through steel pin installation, achieving a reusable, rapidly installable, and structurally sound steel platform system. The application of this new steel platform system ensures the rapid installation and safe, reliable construction of building construction machinery steel platforms, while also meeting the reusability requirements of steel platforms.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
